Question

How do nerve impulses allow us to move our muscles?

Answer 1

Explanation:

Muscles move on commands from the brain. ... When a motor neuron inside the spinal cord fires, an impulse goes out from it to the muscles on a long, very thin extension of that single cell called an axon. When the impulse travels down the axon to the muscle, a chemical is released at its ending.
